If you have Simulink composition models consisting of subsystems or Model blocks, then you can extract the architecture of such a system and use System Composers capabilities to further refine and analyze it.

First, open the Simulink Model

Then Select Export Model to an architecture model

And give the architecture model a name. Select export

The new architecture composition diagram has been created

The individual components have the name of the Simulink model they are linked to under the name of the component along with the Simulink icon in the upper right corner. Simply clicking on it will open the Simulink diagram.

You can now add more components, apply custom properties to elements in the model, perform data driven trade studies and create spotlight views.

This spotlight view creates a simpler diagram containing only the Actuator 2 component and the components it interacts with making it easier to understand the context of the component and reason about the impact a change to this component may have on the system.

This is how you EXTRACT AN ARCHITECTURE FROM AN EXISTING SIMULINK MODEL
